Details

Thomas Sesselmann discovered that the OpenLDAP slapd server
did not properly handle certain modify requests. A remote
attacker could send malicious modify requests to the server
and cause a denial of service. (CVE-2007-5707)

Toby Blake discovered that slapd did not properly terminate
an array while running as a proxy-caching server. A remote
attacker may be able to send crafted search requests to the
server and cause a denial of service. This issue only affects
Ubuntu 7.04 and 7.10. (CVE-2007-5708)

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.10

• slapd - 2.3.35-1ubuntu0.1

Ubuntu 7.04

• slapd - 2.3.30-2ubuntu0.1

Ubuntu 6.10

• slapd - 2.2.26-5ubuntu3.2

necessary changes.
